六下部分参考答案一圆柱与圆锥《面的旋转》第1页 4.提示：饮料罐底面直径是6厘米，每排摆6个，所以纸箱的长度应该是6个6厘米；摆了4排，所以宽应该是4个6厘米；摆了2层，长方体的高应该是2个圆柱的高。

解：长：6×6=36（cm）宽：6×4=24（cm）高：12×2=24（cm）5.提示：圆锥底面直径20厘米与两个圆锥底面间距离1.5米单位不同，先要统一单位。

解：0.2×10+1.5×（10-1）=15.5（m）《圆柱的表面积（2）》第3页 5.提示：圆柱侧面展开后是正方形，底面周长相当于正方形的边长（也就是圆柱的高）。

解：半径：25.12÷3.14÷2=4(cm)表面积：25.12×25.12+3.14××2=731.4944(㎝2)《圆柱的体积（2）》第5页 6.提示：水升高的体积相当于石子的体积，所以计算石子的体积就是计算上升部分圆柱的体积。

解：3.14××5=251.2（）《圆锥的体积》第7页7.提示：水上升的体积相当于圆锥体的体积，先计算出上升部分水的体积，因为圆锥的体积=底面积×高，所以圆锥的高=体积÷（×底面积）。

解：3.14××0.3÷（×3.14×）=10(cm)《练习一》第9页 7.提示：圆锥体的体积=长方体的体积，先求出圆锥的体积，再除以长方体的底面积可以求出长方体的高，也就是“铺多厚”。

解：半径：12.56÷3.14÷2=2（m）×3.14××1.5÷(4×2)=0.785(m)二比例《比例的认识（2）》第13页 4.提示：此题为开放题目，答案不唯一。

根据比例的基本性质内项之积等于外项之积。

（1）∵0.2×12=2.4 ∴答案可以是0.2︰（2）=（1.2）︰120.2︰（3）=（0.8）︰12 0.2︰（4）=（0.6）︰12 等。

小学四年级数学每日一题及解析

9月21日(星期四)数学思考题:在一个正方形的每条边上摆4枚棋子，最少需要多少枚棋子？（利用画图的方法，在正方形的四个角上各摆上2枚棋子，就满足条件了。

）9月22日（星期五）“每日一题”从海门到南通有2条路可走，从南通到如皋有3条路可走，现在小明要从海门经过南通到如皋去，可以有多少种不同的走法？（分析：可以借助图加于分析，很容易知道共有6种不同的走法。

）9月25日（星期一）每日一题你能写出几道没有余数的除法算式吗？□□□÷30=□（分析：这是一道开放题，可以先确定商〈一位数〉，再根据商×30算出相应的被除数）9月26日（星期二）每日一题小明在计算除法时，把除数42写成24，结果得到商17还余19。

你能写出正确的计算结果吗？（分析：除数看作24时，商为17还余19，根据商乘除数加余数求出被除数是24×17+19=427，再用427÷42就能求出正确的计算结果了。

）9月27日（星期三）每日一题有三人流浪在一孤岛，他们造了一条船，但船最多只能载90千克重的东西，他们三人的重量分别是40千克、50千克、60千克。

问他们三人怎样乘船才能安全的回到陆地？（分析：先40千克和50千克的过去，然后回来一个，这里就让40千克的回来。

然后40千克的留下，60千克的过去，再50千克的回来，最后40千克和50千克的一起过去。

）9月28日（星期四）每日一题今年的9月28日是星期四，明年的9月28日星期几？（分析：今年的9月28日到明年的9月28日正好经过1年，也就是365天，365÷7=52（个星期）……1（天）。

星期四加1就是星期五，即明年的9月28日是星期五。

）9月29日（星期五）每日一题一位牛奶商只有容量分别为5升与3升的两个瓶子可供他从牛奶罐中量取客户所需的牛奶。

请问如何利用这两个瓶子，量出一升牛奶，而且不得浪费任何牛奶？（分析：先将3升瓶装满，倒入5升瓶内，再将3升瓶装满，倒入5升瓶内倒满为止，这时3升瓶内剩下1升。
